Description
Technical field
The present invention relates to a kind of pressure-control valve, be specifically related to a kind of pressure-control valve with lubricating function.
Background technology
Pressure-control valve is applicable to most of plant equipment, equally also needs to be provided with pressure-control valve in loading machine. A: close oil-in 11 and be connected with oil-out 12 and lubricated hydraulic fluid port 13 in the time that engine stops burning, retain fluid in oil-in 11 and front oil duct oil circuit and fill up; B: after starting system, oil-in 11 is had to certain back pressure (the first pressure), improve and start output torque to executing agency's efficiency. C: by the second pressure control, when oil-in oil temperature is low, part fluid directly lubricates hydraulic fluid port 13 to lubricated hydraulic fluid port 13 part fluid through rejecting heat to, in the time of high oil temperature, close oil-in 11 and lubricated hydraulic fluid port 13, all fluid is fully dispelled the heat to the high oil temperature fluid of lubricated hydraulic fluid port 13 through radiator. D: by the control of overflow spool pressure, lubricating system has the fluid of certain pressure to go to lubricate, makes lubricant effect reach best, and radiator plays a protective role simultaneously, avoids hypertonia radiator to break.
And loading machine can relate to the cooperation between mechanism in the time of gearshift, mechanism can produce heat in the situation that coordinating operation, and along with the prolongation of running time, temperature can constantly raise, and in the time of excess Temperature, loading machine just easily breaks down. For fear of the generation of above-mentioned situation, need on loading machine, dispel the heat by installation of heat radiator, if but for a long time excess Temperature of radiator itself, also reduction of service life very easily.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of pressure-control valve with lubricating function, and it can be lubricated the coupled parts such as torque-converters, gearbox mechanism.
For solving the problems of the technologies described above, the technical solution that the present invention has the pressure-control valve of lubricating function is:
Comprise valve body 1, valve body 1 inner chamber is provided with controls spool 2 and overflow spool 3; The rear end of controlling spool 2 connects the first spring 5, the first springs 5 by pressure regulation circle 7 and connects the first spring base 6; The front end cavity 9 of controlling spool 2 is connected with oil-in 11; Controlling spool 2 can move backward under the effect of front end oil pressure; Valve body 1 is provided with the first oil-out 12 and the second oil-out 13; The first oil-out 12 is connected with radiator by oil pipe; The second oil-out 13 is connected with treating lubricated parts mechanism; In the time that control spool front end oil pressure is the first pressure P 1, controls spool 2 and move backward, until oil-in 11 is connected with the first oil-out 12; In the time that control spool front end oil pressure is the second pressure P 2, the second oil-out 13 is opened; The second oil-out 13 is connected with the front end of overflow spool 3 place cavitys; The front end of overflow spool 3 place cavitys is provided with oil-recovery tank 14; The rear end of overflow spool 3 connects the second spring base 10 by the second spring 8; Overflow spool 3 can move under the oil pressure effect in the second oil-out 13 backward, until the second oil-out 13 is connected with oil-recovery tank 14.
Fluid enters from described oil-in 11, after promotion control spool 2, moves oil-in 11 is connected with the first oil-out 12, and fluid enters radiator through the first oil-out 12 and oil pipe; Fluid refluxes after by radiator, then enters and treat lubricated parts mechanism through the second oil-out 13.
In the time that the front end oil pressure of described control spool 2 is greater than the elastic force of the first spring 5, oil liquid pressure makes to control spool 2 and moves backward, thereby makes the oil liquid pressure in oil-in 11 stable, to realize the adjusting to pressure.
In the time that the oil liquid pressure in described the second oil-out 13 is greater than the elastic force of the second spring 8, oil liquid pressure moves overflow spool 3 backward, until the second oil-out 13 is connected with oil-recovery tank 14, now the fluid in the second oil-out 13 enters oil-recovery tank 14, thereby make the oil liquid pressure in the second oil-out 13 stable, to realize the adjusting to lubricating oil pressure.
The technique effect that the present invention can reach is:
The present invention can carry out cooling processing by radiator, and it is more remarkable to be lubricated operation lubricant effect to the parts such as torque-converters, gearbox mechanism with fluid after heat radiation.

Detailed description of the invention
As shown in Figure 1 and Figure 2, the present invention has the pressure-control valve of lubricating function, comprises valve body 1, and valve body 1 inner chamber is provided with controls spool 2 and overflow spool 3;
Controlling spool 2 is contained in valve body 1; The front end of controlling spool 2 is provided with bolt 4, and bolt 4 is fixedly connected with valve body 1; The rear end of controlling spool 2 connects the first spring base 6 by the first spring 5;
Control between spool 2 and the first spring 5 and be provided with pressure regulation circle 7;
The front end cavity 9 of controlling spool 2 is connected with oil-in 11; Controlling spool 2 can move backward under the effect of front end oil pressure; Valve body 1 is provided with the first oil-out 12 and the second oil-out 13; The first oil-out 12 is connected with radiator by oil pipe; Other parts mechanisms such as the second oil-out 13 and torque-converters, gearbox etc. are connected;
In the time that control spool front end oil pressure is the first pressure P 1, controls spool 2 and move backward, until oil-in 11 is connected with the first oil-out 12; In the time that control spool front end oil pressure is the second pressure P 2, the second oil-out 13 is opened; Wherein, first pressure P 1 < the second pressure P 2;
The second oil-out 13 is connected with the front end of overflow spool 3 place cavitys; The front end edge of overflow spool 3 place cavitys is circumferentially formed with oil-recovery tank 14; The rear end of overflow spool 3 connects the second spring base 10 by the second spring 8;
In the time that the oil liquid pressure in the second oil-out 13 is greater than the elastic force of the second spring 8, oil liquid pressure moves overflow spool 3 backward, until the second oil-out 13 is connected with oil-recovery tank 14, now the fluid in the second oil-out 13 enters oil-recovery tank 14, thereby make the fluid amount in the second oil-out 13 controlled, to play pressure regulation effect.
Operation principle of the present invention is as follows:
Fluid enters from oil-in 11, promotes to control after spool 2 to move oil-in 11 is connected with the first oil-out 12, and fluid enters radiator through the first oil-out 12 and oil pipe and carries out cooling;
In the time controlling spool 2 and cause due to fluid overfill that pressure is excessive herein, part fluid starts to push the first spring 5, Oil shocking is on pressure regulation circle 7, because pressure regulation circle 7 is connected with the first spring 5, so under oil pressure effect, control spool 2 and start to move backward, oil-in 11 is communicated with the first oil-out 12, and pressure is thereupon adjusted;
When fluid is undertaken after cooling processing by radiator, fluid starts to reflux, and fluid is back in lubricant reservoir, then enters other parts mechanisms such as torque-converters, gearbox through the second oil-out 13, and said mechanism is lubricated;
When the fluid of the second oil-out 13 is filled too fast while causing that pressure rises sharply herein, after starting, moves by the second spring 8 of overflow spool 3 its inside of extruding, in the time that the front end of overflow spool 3 retreats to oil-recovery tank 14 position, the oil having more is got back to oil-recovery tank 14 just in time can regulate high-pressure;
When the fluid flowing out from the second oil-out 13 completes lubrication operation, fluid all flow in the casing of gearbox and stores.
